使用Lua I / O函数创建新文件 [英] Creating new files with Lua I/O functions

问题描述

我开始了解io。函数，我试图在我的代码中实现它们。我已经搜索过这个问题的答案，似乎没有什么可以明确表示是或否，或者至少我没有看到一个。我希望有人能够知道答案，并能够帮助解决这个问题。

I'm starting to learn about the io. functions, and am trying to implement them in my code. I've searched for the answer to this and nothing seems to give a clear cut yes or no, or at least I don't see one. I'm hoping someone here will know the answer and be able to help with this.

我想创建一个文本文件，随着时间的推移我可以写入。它基本上是一个日志，我将附加输出行。显然io.open（textfile.txt）不会创建文件，或者它出现。

I'm wanting to create a text file that I can write to as time progresses. It'll basically be a log to which I'll be appending lines of output. Apparently io.open("textfile.txt") does not create the file, or so it appears.

有没有办法在Lua中创建一个可以的文本文件以后可以用io.read/write访问？另外，在打开或创建新文本文件之前，是否需要调用io.close（）？我感谢任何帮助。谢谢！

Is there a way to create a text file in Lua that can later be accessed with io.read/write? Additionally, do I need to call io.close() before opening or creating a new text file? I appreciate any help given. Thanks!

推荐答案

您需要打开写的文件，如下所示： F = io.open（ TextFile.txt的， W）。然后使用 f：write（）写入内容。完成写作后，请致电 f：close（）。

You need to open the file for writing as follows: f=io.open("textfile.txt","w"). Then use f:write() to write stuff to it. When finished writing, call f:close().
